The backend of my Senior Thesis for Barrett, The Honors College at Arizona State University (Jan 2015 - Nov 2015). The REST API and other server functionality. Other server functionalities include a cosine similarity article comparator that compares a set of articles to each other and chooses the 4 most diverse ones (using standard deviations from the average cosine similarity) and a Twitter trending/breakout detection algorithm using the 3 sigma method.
The iOS frontend for that consumes this backend can be found here:
